Device and method for flexible connection between masonry filler wall and main body frame

Abstract

The invention relates to a device for flexible connection between a masonry filler wall and a main body frame. The device consists of a connecting member A and a connecting member B, wherein the connecting member A is embedded in a frame column and a frame beam, and the connecting member B is connected with the connecting member A through a sliding groove and a sliding block. During the building of the filler wall, firstly, the connecting member A is arranged on a rod placement of the frame, an opening of the sliding groove of the connecting member A is enabled to be tightly attached to a formwork, and then, concrete is poured; the formwork is removed when the concrete reaches design strength, and the connecting member B is connected with the connecting member A. During the building of a wall body, a fiber grille is cut out and is tiled in mortar, and the two end parts of the fiber grille are turned over along the height direction of edge building blocks so as to be embedded into next layer; after the building of the wall body is completed, a flexible sealing material is filled in gaps between the wall body and the frame. The connection between the filler wall built by the device and the main body frame is firm, out-of-plane is stable, and the earthquake resistance is high; the frame column and the filler wall do not interact, so that the problem that a major structure is affected by the filler wall built settlement is solved; in a structural earthquake-resistant design, a structural natural vibration period reduction coefficient is not required to be introduced, and thus the design is facilitated.

Description

technical field [0001] The invention relates to a building structure, in particular to a flexible connection device and method for a masonry filling wall and a main frame. Background technique [0002] There are two ways of disengagement connection and rigid connection between the masonry infill wall and the main frame. [0003] The disconnection method is often not adopted due to the outstanding out-of-plane stability of the infill wall. [0004] Rigid connection is divided into two types: tie bar pre-embedded method and tie bar chemical planting method. [0005] The pre-embedding method of tie bars is to pre-embed tie bars in the frame columns. Due to the error of masonry in actual construction and the difference in the modulus of the blocks, the positions of the pre-embedded tie bars and the horizontal mortar joints often do not correspond. The tie bars had to be artificially bent, which changed its force transmission path and mechanical performance, reduced the effect ...
